The invention relates to an organic light-emitting diode, known under the abbreviation OLED, and to a method for the production of such an organic light-emitting diode. According to the invention, an OLED or organic light-emitting diode having an emitter layer (5) is produced, said emitter layer emitting white light in particular. The emitter layer (5) is arranged within a lossy, optical resonator. The optical path length between the two reflecting layers of the resonator determines the color of the light emitting from the optical resonator and, consequently, from the light-emitting diode. In order to be able to create a variety of colors, there must be different optical path lengths between the two reflecting surfaces. The correspondingly different distances can be produced in only one work step, in contrast to the prior art, by a photolithographic method. The result is an organic light-emitting diode having a lossy optical resonator, having an emitter layer (5) and a layer (4) that can be photolithographically structured. Said layer (4) is comprised of photochemically curable materials. Organic light-emitting diodes according to the invention can be used in light sources, lighting, sensors or spectrometers.
摘要:
The invention relates to electronic devices whose electronic properties can surprisingly be improved to a significant degree by inserting at least one crosslinkable polymeric buffer layer, preferably a cationically crosslinkable polymeric buffer layer, between the conductive doped polymer and the organic semiconductor layer. Particularly good properties are obtained with a buffer layer in which crosslinking is thermally induced, i.e. by raising the temperature to 50 to 250° C. Alternatively, crosslinking can be radiation-induced by adding a photoacid. Moreover, such a buffer layer can be advantageously applied by means of printing techniques, especially inkjet printing, as the ideal temperature for the thermal treatment is independent of the glass transition temperature of the material. This avoids having to rely on material that has a low molecular weight, making it possible to apply the layer by means of printing techniques. The next layer (the organic semiconductor layer) can also be applied with the aid of different printing techniques, particularly inkjet printing, because the buffer layer is rendered insoluble by the crosslinking process, thus preventing the buffer layer from solubilizing thereafter.

The present invention describes a novel method for crosslinking organic semiconductors and conductors by initiating this crosslinking in an autophotosensitised manner. It furthermore describes the production of organic electronic devices through the use of this crosslinking method. The properties of the electronic devices are thereby improved.

Z is —O—, —S—, —CO—, —COO—, —O—CO— or a bivalent group —(CR1R2)n— in which R1 and R2 are hydrogen, alkyl, alkoxy, alkoxyalkyl or thioalkoxy group, aryl or alkenyl, in each of which one or more hydrogen atoms may be replaced and one or more nonadjacent carbon atoms may be replaced, and n is an integer from 1 to 20. X is a bivalent group —(CR1R2)n— and, with the proviso that the number of these A groups is limited by the maximum number of available substitutable hydrogen atoms. The invention also relates to their use for producing optionally multilayered structured light emitting diodes, lasers, solar cells, waveguides or integrated circuits.
